IMPROVEMENT IN MACHINES FOR MAKING FASTENINGS FOR THE SOLES 0F BOOTS ANDSHOES.-

Specification forming part of Letters Patent No. 188,354, dated March13, 1877; application filed February 3, 1871.

; To all whom "it may concern Be it known that I, LoUIs GODDU, ofWinchester, in the county of Middlesex and State of Massachusetts, haveinvented a new and useful improvement, being a Machine for MakingFastenings for the Soles of Boots and Shoes in integral wire or rods ofdistinct nails orpegs, having heads and points, of which the followingis a specification:

The article to be manufactured consists of a sole-fastening for bootsand shoes and other purposes, formed in continuous lengths of integralwire or rods of distinct nails or pegs having heads and points, andadapted to be fed by the inserting machine, and severed into nails orpegs, such severance being made either before or after the nail has beeninserted, the heads of the integral nails or pegs serving as the meansfor making and governing the feed, and determining the point at whicheach nail is separated from the contin uous wire.

The machine for producing this article forms the subject of my presentinvention.

I employ rolls of small diameter, having dies of suitable coincidentindentations the counterpart of the nail to be made, and incased insolid bearings, which support them directly above and below where thepressure is applied to keep the surface of the rolls in contact. Atright angles to these rolls the passage for the wire is made inandthrough the solid incasement or bed, so that the wire can be fed to,and carried from, the rolls as it is formed into nails or pegs. Thecoincident indentations of the rolls are corrugated to effect the feedof the Wire, and to form corrugations upon the side or sides of theshanks of the integral nails or pegs, if desired. The surfaces of therolls meet and join in their incased solid bearings; and to obtain suchan arrangement of the rolls, their incased bed is divided into twosections, secured together by strongscrew-bolts, by which they can beadjusted as may be required to adapt the rolls for their proper work.

Motion is imparted to one of the rolls, which. is connected by equalgear to the other roll, and the effect of the corrugations of the rollsis to draw the wire between them informing the nails, the gearsbeingarranged and adaptedto make and maintain the coincident indentations inthe wire by maintaining the :00- incidence of the head-formingindentations in the rolls. The arrangement of shoulders formed by theequal gears and of an outside fixed cap prevent the rolls from havingany longitudinal movement. Atrimmin'g-pla'te is arranged at theexit-opening of the wire-passage in the solid bed, for taking off anyfine burr on the edges of the wirewhich might be left upon it in passingthrough the rolls.

Two or more sets of dies can be made on i the rolls for separate use,thus saving the expense of making new rolls when one set is worn toomuch for use, the operation being conducted with one set of dies at atime, so thata single set of rolls can be used to-increase the capacityof the machine, while their incased bed is adapted for the removal ofsuch rolls as may be required.

The wire is fed from a coil into the machine, I

and coiled as it is delivered therefrom in continuous lengths of wire orrods of distinct headed nails or pegs. p

The effect of the small rolls .is to stretch the wire in the directionof its length, and not to make any part of the nail .of greater widththan the diameter of the wire, and to accomplish this it is of absoluteimportance that the rolls should be supported ,so as to prevent anyspringing by the pressure against them in rolling the wire with itsheads, for the least springing ,or yielding of the rolls would cause themetal to spread, and the nails to be of irregular shape and useless.

completely incase them'and form their bearings, having bored-outcavities or bearings, into which the rolls are exactly fitted, so as toexpose a small portion of their circumference, and to allow them to meetwhen joined in their solid beds. These die-rolls are made of smalldiameter-say, about three-quarters of an inch, and their pressure mustbe great enough to reduce the thickness of the wire, and form the headsby stretching the wire, and not byflattening or making any part of thenail of greater width than the wire. It is the small size of the rollsthat enables me to accomplish this result, and in the employthe rollsstated will give four nails. The

lengthof the nail or peg to be formed, however, will determine thismatter. Each groove is divided into an equal number of taperingindentations with cross-cavities, so that when the rolls are properlygeared these indentations will be coincident, and form the heads andpoints of the nails alike on both sides of the wire, the heads andpoints joinin g throughout the continuous length, and for this purposethe taper of the indentations must be so gaged that the heads and pointsof each nail shall be joined. with the required strength to allow thewire to be coiled, handled, and operated in the inserting-machine. Thewirepassage e is formed equally in the solid beds in line with the dies,forming a straight groove extending from both-sides of the rolls throughwhich the wire is fed and supported, being entered from one side of thesolid bed, and passing out at the other, producing in effect an inclosedway for the wire into and from the dies.

The'surfaces of the indentations or dies have transverse corrugations,which serve to draw the wire uniformly through the rolls, and tocorrugate the sides of the shank of each nail, leaving only a plainspace for the clinching-point.

The construction of these dies may, of course, be adapted to the form ofany style of nail or peg, as, for instance the head may be formed onlyon one side of the wire, as in Fig.

6, in which case the rolls would nothave coincident indentations. Eachdie-roll has its own solid bed or metal case, and these are joined justin line with the circumference of the JOllS with true surfaces, andsecured together by strong screw-bolts O, which pass vertically atsuitable points through screwthreaded openings in the upper, and intoscrew-threaded openings in the lower, solid bed, holding them togetherso as' to resist thepressure upon the rolls. Dowel-pins f are providedon one 'of these sections or beds, to enter corresponding holes in theother, to efi'ecta perfect matching of the dies.

The die-rolls-are fitted endwise into their bearings, and are gearedtogetherby equal gears g h, upon their ends, outside of the solid beds,by which their nail-forming indentations are kept coincident. Thedie-rolls are prevented from having any endwise movement by means of thegears being a little greater in diameters than their rolls, to formshoulders, which bear against the sides of the solid beds, and a cap, D,firmly secured to one of the beds, against which the outer ends of thegearswork, so that, when properly seated,

the rolls are held truewith their dies.

I prefer to make the lower roll the driving- I roll, and to this thepower is applied by joining an extension, E, of said roll, toa'driving-' shaft suitably arranged and driven, the connection beingmade by fitting the roll-extension into a socket in the driving-shaftand keying the two together, or by any other suitable means.

I combine with the exit end of passage for the integral nail-wire aplate, F, having an opening coincident with such nail-passage, theobject of which is to trim off any fine burr or edge which might be leftupon the wire in passing through the rolls, and thus deliver thecontinuous length of integral nails finished and complete, the openingin such trimming-plate being just equal to the diameter of the headsformed upon the wire by the dies, so that the opposite edges of the wirewill be trimmed, as stated, as it leaves the solid bed.

By this method of rolling, the wire is not flattened, but simplystretched, and the malleability of the metal is thereby preserved, sothat the nail-wire requires no annealing, and the nails will readilyclinch when driven.

I have shown the rolls with a single die, but

it is obvious that two or more sets of dies or diegrooves andwire-passages can be arranged upon such rolls and solid beds, betweenthe fastening screw-bolts, so that when one set of the dies is wornanother can be used, thus adapting the same roll and bed-bearings toincrease the capacity of the machine, and save the expense of making newrolls until all the dies are worn too much for use, when the rolls canbe removed and renewed, using the same bed-bearings, which, being ofsteel, and the bearings of the rolls equal throughout their length, willlast a long time.

Suitable appliances are arranged to deliver the wire from a coil intothe wire-passage and the dies, and to receive and coil the completednail-formed wire as it leaves the trimming-plate.

The screw-bolts which secure the two bedsections together have longloosely fitting washers, upon which the screw -heads are clamped, tomake the fastening more secure.

The drawings represent the machine in full size, and with the solidbearin gs for the rolls of rectangular form; but these hearings may beof any form and construction, so long as headed sole-fastenings incontinuous lengths of wire or rods of distinct nails or pegs, ofdierolls, embedded and incased in solid bearings, to give the requiredsupport, with a feed-passage for the wire made through said solid beds,across and in line with the meeting-surfaces of said rolls, for theentrance of the wire to and its passage from said embedded dierolls.
